👋

Hello, I'm Sang June Rhee, and you can call me Josh. I'm a Softwar Engineer, Student, and Problem Solver. I enjoy building sites, apps, & solving challenge problems. I have a lot of experience in software development specially React, Typescript, Python, Node.js, and Serverless (AWS Lambda).

About Me

I graduated from Georgia Tech with Computer Science degree. I'm on a mission to use technology to help people and make a difference with an impact. I'm an open-source contributor who loves improving the developer community one pull request at a time, and a frontend nerd who can't resist trying out a new JavaScript framework or library after work. Especially if it promises some new feature or improvement that I needed yesterday.

When I'm not coding, I mostly spend my time with my wife and child. If I am alone, I enjoy watching other engineers Tech Talk or reading Engineering Blog Post to learn how they solve their technical problems. I learned a lot from Netflix Engineering, and AWS Youtube channel.
